A Starlight Feathertouch deluxe focuser upgrade for the Altair 115-805 EDT APO. This is simply the best focuser we have been able to source for our high quality triplet APOs, and a work of art in it's own right.

This package includes

1) the focuser

2) a custom designed focuser rotator/OTA adaptor to fit the telescope. Simply screw on the rotator, connect the focuser, and you're ready to observe. Please enquire before ordering with the serial number of your refractor. Depending on the model of refractor you have, we may need to supply a UK made OTA adapter to fit between focuser and optical tube with the correct thread.

Optional: A separate rear end-cap adapter is available to fit the Altair Planostar Large 60mm Field Flattener directly to the focuser (you can see an example of how this works in the product image gallery). Order the adapter by clicking on the dropdown menu before adding the product to your cart.

Automation: The Starlight Feathertouch focuser is not only a joy to use manually! It can also be driven by super-accurate stepper motors, using our Altair-Rigel USB nStep motor focuser system and the Starlight Feathertouch adapter bracket. (See associated products below). With the USB autofocuser, precise manual focusing can be achieved using the hand controller for high power planetary observation, or you can fully automate your focuser via a USB connection and a PC using popular astronomy focusing programs and ASCOM. The high resolution stepper motors are capable of procise control with fractions of a millimetre. A separate temperature compensation probe is available, to ensure focus is always perfectly maintaned, regardless of external temperature changes.

Please enquire before ordering with the serial number of your refractor. Depending on the model of refractor you have, we may need to supply a UK made OTA adapter to fit between focuser and optical tube with the correct thread.
